What are 4 characteristics of all non metals?
Properties of Nonmetals
Nonmetals have high ionization energies and electronegativities. They are generally poor conductors of heat and electricity. Solid nonmetals are generally brittle, with little or no metallic luster. Most nonmetals have the ability to gain electrons easily.
Which of the following is characteristics of non metals?
Non metals are usually poor conductors of heat and electricity. They are non-lustrous, non-sonorous, non-malleable and are coloured.
What are 5 characteristics of non metals?
Nonmetals engage in covalent bonds, form brittle fragile compounds, have low melting/boiling points, have high ionization energies and electronegativity, and are poor conductors of electricity.
What are the 3 characteristics of metals?
metal, any of a class of substances characterized by high electrical and thermal conductivity as well as by malleability, ductility, and high reflectivity of light.
Which is not a property of non-metals?
Non-metals have a dull appearance. Non – Ductile cannot be drawn into wires. Hence Conductors are not the property of Non-metals.

What are 3 characteristics of non-metals?
Elemental Properties
In the elemental form, non-metals can be gas, liquid or solid. They aren’t shiny (lustrous) and they don’t conduct heat or electricity well. Usually their melting points are lower than for metals, although there are exceptions. The solids usually break easily, and can’t bend like metals.
What are three characteristic properties of non-metals?
In general, non-metals are brittle, dull, and poor conductors of heat and electricity. They tend to have lower melting points than metals. Most of non-metals exist in two of the three states of matter at room temperature: gases and solids, except bromine, which exists as a liquid.

What are 5 characteristics of metals?
- good conductors of heat and electricity.
- ductile (can be drawn into wires) and malleable (can be hammered)
- metals are solid at room temperature (except Mercury, it is a liquid state)
- high tensile strength.
- usually lustrous/shiny.
What are the characteristics of metals and non metal?
Metals tend to be hard, metallic-looking solids, with high electrical and thermal conductivity values and high melting and boiling points. Nonmetals tend to be softer, often colorful elements. They may be solids, liquids, or gases.
